▼ Methane is the second most important greenhouse gas after CO2 and affects atmospheric temperatures directly and indirectly. Through its chemical loss in the atmosphere, methane also influences tropospheric ozone concentrations, a major air polluter. Experiments have been performed with a chemistry-climate model investigating the effects of source and sink changes on atmospheric methane in a present day (2000) and future (2100) climate. The model setup has been altered so that methane emissions are accounted for rather than using a fixed surface concentration boundary condition. Furthermore, a new chemistry scheme has been implemented into the model in which oxidant fields are prescribed removing methane’s self-feedback. This complements the existing, interactive chemistry scheme. Interactive methane concentrations and its atmospheric lifetime were found to be slightly low biased relative to observations with a source strength of 548 Tg(CH4) yr-1, in line with recent estimates. This low bias may be linked to tropospheric ozone, NOx and CO biases in the model, all influencing the tropospheric OH radical, methane’s major sink. OH was high biased relative to observational estimates, a common feature of chemistry-climate models. Methane emissions were increased to 585 Tg(CH4) yr-1 with a latitudinal shift to larger tropical emissions. This increase resulted in excellent agreement between modelled and observed methane levels, both globally and in the latitudinal gradient. The 7% methane emission increase also increased tropospheric ozone levels. This highlighted methane’s negative impacts on air quality, particularly important because of recent and projected methane emission increases. Probing the sink effect on atmospheric methane levels with the new non-interactive chemistry scheme showed that reducing the OH sink strength and altering its latitudinal distribution improved global methane levels and led to reasonable agreement with observations. However, the latitudinal gradient of non-interactive methane was overestimated suggesting that either the source or the sink distribution require adjustment. Analysis furthermore showed that a tropical shift of methane emissions only slightly improved the latitudinal gradient of non-interactive methane. Future climate experiments were performed which show that the OH sink increase due to higher temperatures (and thus larger tropospheric water vapour content) is counteracted by projected methane emission increases. While projected CO emissions decreased to the end of the 21st century, model calculations here showed that the tropospheric CO burden increased due to chemical production during methane loss. These experiments highlighted that methane emission mitigation is not only beneficial in slowing climate warming but also in improving air quality, affecting the ozone budget.

▼ Roadside vehicle remote sensing is a common method to evaluate criteria pollutant emissions from vehicle fleets. A popular application of this method is the evaluation of the effectiveness of emissions reduction treatments (e.g. vehicle Inspection and Maintenance (I/M) programs) by comparing the emissions from the treated (experimental) fleet to those of an untreated (reference) fleet. Since no two large vehicle fleets are identical, the reference fleet is produced synthetically by application of correction factors. Current federal guidance assumes that closely located experimental and reference fleets behave similarly if normalized by model year distribution and Vehicle Miles Traveled (VMT). However inconsistency in the results from these evaluations questions whether these controls are sufficient to estimate emission reductions attributed to I/M with an acceptable level of uncertainty. In addition to age and mileage accumulation, emissions from vehicle fleets can be influenced by differences in a variety of other factors including differences in fuels and usage patterns and socioeconomic factors that can influence fleet composition and maintenance trends. This study evaluates the influence of variety of these factors in determining the reference fleet correction factors for the Macon and Augusta Georgia fleets for evaluation of the Atlanta, GA I/M program over a twelve-year period from 1998 to 2010. A series of "null" experiments were conducted to evaluate factors that might affect emissions across vehicle fleets of the same model year distribution. The results showed that in addition to model year and VMT, the reference fleet also required normalization by vehicle type, Vehicle Specific Power (VSP) and, in certain cases, fuel composition to produce a reliable reference fleet correction factors.

▼ Significant growth in the scale of climate action is witnessed globally as cities, nations and environment agencies implement mitigation strategies and try to meet their ambitious emission reduction goals. As a result, many sectors have experienced significant emission reduction in recent years, except for transportation. Over the past two decades, transportation emissions, primarily driven by the sector’s high dependency on fossil fuels, are continuously rising. Cities are the hotspots as they drive the majority of transportation demand. Various policies and local climate action strategies are already in place to mitigate emissions, including but not limited to reducing auto dependency and the use of alternative modes and cleaner fuel. However, limited means are available to quantify the effectiveness of these strategies. While various methods and guidelines inform national emission estimation processes, limited tools are available for cities to report their local emission inventory. The purpose of this research, therefore, is to prepare a methodology which can be adopted by local authorities to better report and manage local transport emissions at the municipal and regional scale. The Environmental Protection Agency’s (EPA) Motor Vehicle Emission Simulator (MOVES) is customized to develop emissions inventory at the disaggregated level while capturing local transportation characteristics. The model is applied to a case study area selected in the City of Waterloo, and emissions (CO2 equivalent) are estimated from different vehicle types and vehicle activities. The emission results obtained are extrapolated to the city scale, and different scenarios are explored to identify the potential for Electric Vehicles (EVs) to contribute to further emission reduction. Transportation sector emissions for the City of Waterloo are projected for 2031 and 2051 based on increased traffic and commercial vehicle activity share. Research findings suggest that the majority of Waterloo’s transportation sector emissions are from light-duty vehicles. Heavy and medium-duty vehicles, on the other hand, have a smaller share in total vehicle activity but are significant contributors to emissions, which makes their electrification critical to the City’s emission reduction plan. To meet the City’s long-term emission reduction goals, an ideal transport emissions profile is created considering the complete and partial electrification of different vehicle types. The research findings suggest that to achieve the City of Waterloo’s 2050 emission reduction target, 100% electrification of light and medium-duty vehicles and 25% electrification of heavy-duty vehicles would be required. However, this transition to an electric fleet is quite challenging as economic, policy and infrastructure barriers to market adoption of electric vehicles, especially medium and heavy-duty vehicles need to be addressed.

▼ United States natural gas dry production increased by 47% between 2005 and 2015 due to the widespread use of horizontal drilling and hydraulic fracturing to extract gas from shale and other tight formations. Natural gas production and consumption is projected to continue to increase for the foreseeable future. In 2016, the natural gas supply chain delivered 29% of the energy used in the U.S., and natural gas surpassed coal as the leading electricity generating source for the first time in U.S. history. When combusted, natural gas produces less CO2 per unit energy released compared to coal or petroleum. However, uncombusted methane (the primary component of natural gas) has a global warming potential 30 times higher than CO2 on a 100 year time horizon (including oxidation to CO2, but excluding climate-carbon feedbacks). Therefore, the net greenhouse gas impacts resulting from displacement of coal and petroleum by natural gas depend on the emission rate of uncombusted natural gas. Short term climate benefits resulting from coal substitution, for example, are lost if the net rate of methane (CH4) emission from the natural gas supply chain exceeds 3—4% . Three studies were conducted to quantify CH4 emissions from the natural gas industry. In particular, these studies focused on quantifying emissions from the gathering and processing sector and reconciling emissions estimates developed using top-down (tracer flux and aircraft) vs. bottom-up (on-site component-level) measurement approaches. In the first study, facility-level CH4 emissions measurements were made at 114 natural gas gathering facilities and 16 processing plants in 13 U.S. states during a 20-week field campaign conducted from October 2013 through April 2014. Measurement results were combined with facility counts obtained from state air permit databases and national inventories in a Monte Carlo simulation to estimate CH4 emissions from U.S. natural gas gathering and processing operations. Annual CH4 emissions from normal operations at gathering facilities totaled 1699 Gg (95% CI=1539—1863 Gg), while normal operations at processing plants totaled 505 Gg (95% CI=459—548 Gg). CH4 emissions from abnormal operations at gathering facilities were estimated in a separate Monte Carlo simulation based on field observations and a sub-set of field measurements. These emissions totaled 169 Gg (+426%/-96%). In the second study, coordinated dual-tracer, aircraft-based, and direct component-level measurements were made at midstream natural gas gathering and boosting stations in the Fayetteville shale in Arkansas, USA. On-site component-level measurements were combined with engineering estimates to generate comprehensive facility-level CH4 emission rate estimates ("study on-site estimates (SOE)") comparable to tracer and aircraft measurements. Concurrent measurements at 14 normally-operating facilities showed a strong correlation between tracer and SOE, but indicated that tracer measurements estimated lower emissions (regression of tracer to SOE=0.91 (95% CI=0.83—0.99,… Advisors/Committee Members: Marchese, Anthony J.

Global warming that occurs due to emissions from a country or a country group was studied from two different points of view. Firstly, warming effect caused by Finnish emissions from 1900 to 2100 was assessed using a model that describes removal of greenhouse gases from the atmosphere by pulse response functions, and calculates the radiative forcing caused by an increase in atmospheric concentration. Secondly, Finland's share of global emissions was assessed for the time period during which detailed greenhouse gas inventories were available, i.e. from 1990 to 2003, taking into account uncertainties in emission estimates. The uncertainty estimate was made using literature, measurement data and expert judgement on input parameter uncertainties. Stochastic simulation was used to combine the uncertainties. In addition, uncertainties in different emissions trading schemes were compared at EU level. Greenhouse gases covered by the study were those included in the Kyoto Protocol, i.e. carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs) and sulphur hexafluoride (SF6). Sectors covered were energy, industry, transportation, agriculture and waste. LULUCF sectors (land-use, land use change and forestry) were covered more superficially. Finnish greenhouse gas emissions in 2003 were 86 Tg CO2 eq (without LULUCF). According to the results, 95% confidence interval of this figure lies between 82 and 92 Tg CO2 eq. This represents a share of 0.2-0.3% of global emissions. In the same year, Finland's share of global population was 0.1% and share of global GDP 0.4%. The most important contributors to uncertainty were N2O emissions from agricultural soils, N2O from nitric acid production and CH4 from landfills. Inclusion of LULUCF categories in the inventory increased relative uncertainty of net emissions notably (emissions in 2003 were 68 Tg CO2 eq with a 95% confidence interval of 58 to 78 Tg CO2 eq). According to the radiative forcing calculations, forcing caused by Finland will increase from 3 mWm-2 in 1990 to 6-11 mWm-2 by 2100, depending on emission reduction strategies applied, and technological development. In 1990 Finland's share of global radiative forcing was estimated at 0.18% and by 2100 it will decrease to 0.13%, due to increase in global emissions. The results revealed that Finland's share of radiative forcing was smaller than the share of emissions. This was due to Finland's relatively short emission history. It was concluded that uncertainty in EU emissions trading scheme for CO2 (2005-2007) contains rather small uncertainties (±3% based on uncertainties in inventories), but the extension of emissions trading scheme to cover other sectors or gases is likely to increase the uncertainties (up to 21% in Kyoto emissions trading scheme). Both radiative forcing and uncertainty assessment models developed in the thesis can be used in decision making, e.g. for comparing different emission reduction strategies and for planning of future climate commitments.

▼ A well-known issue of tailings is that they have poor consolidation properties, which, in situ, may require several decades or more before the material can be reclaimed. With the accumulation of tailings in the tailings ponds, one unintended consequence of this long-term storage is the evolution of emissions in the ponds. Studies in the last decade have indicated that methane, a greenhouse gas, is produced by methanogen microorganisms in the tailings and that emissions are more readily stimulated by the hydrocarbons in naphtha diluent that is leftover from the bitumen extraction process. More recent studies have also found black, sulfidic zones in the tailings where toxic, hydrogen sulfide gas may be being produced in considerable amounts, but it is unknown how much hydrogen sulfide or other reduced sulfur compound emissions are being released from the ponds or whether these emissions are also stimulated by naphtha diluent. The objectives of this study were as follows: 1) Determine whether there are advantages to further reducing the diluent concentrations in the tailings with respect to methane, carbon dioxide, and reduced sulfur compound emissions; 2) Between methane, carbon dioxide, and reduced sulfur compound emissions, which are the most concerning quantity wise under a worst case, high diluent scenario; and 3) Aside from diluent, are there other chemical factors that play a role in the types of emissions generated from tailings. A mesocosm experiment was conducted using Suncor Energy Inc. Pond 2/3 mature fine tailings, pond water (Pond 2/3 or surrogate pond water), with naphtha diluent amendments of 0% w/v, 0.2% w/v, 0.8% w/v, and 1.5% w/v. Chromatography gas analysis revealed that all greenhouse gases and reduced sulfur compound emissions increased with increasing naphtha diluent concentrations. Therefore, further reducing the concentration of residual diluent in the tailings ponds is anticipated to decrease the amount of greenhouse gases and reduced sulfur compound emissions that are produced in tailings. With respect to the quantities of emissions produced, at a worst-case diluent scenario of 1.5% w/v, methane emissions were the highest, followed by carbon dioxide, and then the combined amount of reduced sulfur compounds. Within the reduced sulfur compounds, amounts emitted from highest to lowest were in the order of hydrogen sulfide and 2-methylthiophene > 2,5-dimethylthiophene > 3-methylthiophene > thiofuran > butyl mercaptan > carbonyl sulfide, with hydrogen sulfide and 2-methylthiophene combined making up 81% of the total reduced sulfur compound emissions. The remaining sulfate concentrations within the tailings samples was also an important factor with regards to the types of emissions produced as there was a system shift from sulfur emissions production to methanogenesis after sulfate became depleted. Lastly, our results indicated that hydrogen sulfide, methane, and carbon dioxide were produced from biological sources associated with the mature fine tailings whereas the remaining reduced…

▼ Australia is a large global energy supplier. It is the world's largest coal exporter and the second largest Liquified Natural Gas (LNG) exporter, leveraging the technological improvements to extract unconventional gas. A lack of understanding fossil fuel extraction emissions and the absence of regulation to effectively monitor these emissions impacts the accuracy of the emission inventory of the extracting country. It is also sometimes suggested that net fossil fuel exporters induce higher overseas greenhouse gas emissions by their production and export activities. In Australia these cross-boundary effects of both the induced domestic emissions due to new gas exports and the potential contributions to overseas emissions from burned fossil fuels are clearly important to inform any policy discussions. Firstly, Australia allows for the extraction of coal and gas that is exported and subsequently burned by importing nations, causing emissions in those nations. Australia's historical and current emissions from fossil fuel production are unknown. Also, there is no database available that allows allocation of current world emissions and historical emissions by fossil fuel producing country, as so far historical estimates have either looked at territorial or consumption based emissions. This despite the fact that discussions on historical responsibility for climate change gain new traction with every major climate-related disaster and the question of who might pay one day. Secondly, there is a need to better understand the fugitive emissions from unconventional natural gas extraction. Over one third of Australian gas production comes from coal seam gas extraction and the vast majority is exported, but estimates of the fugitive emissions from unconventional gas infrastructure are predominantly relying on possibly outdated emission factors. This is despite the empirical evidence from the United States that fugitive emissions from unconventional gas are much higher in various sedimentary basins. Furthermore, the reported fugitive emissions from gas production in the Australian emission inventory are much lower than those of other gas producing nations. There is little data on the fugitive emissions from Australian unconventional gas developments. The lack of emission data fuels the possibility that emissions are larger than anticipated given the amount of infrastructure, the atypical extraction process of coal seam gas and the local geology. Data on, and understanding the scale of, migratory emissions is lacking completely. Migratory emissions refer to methane emissions that leak through faults and stratigraphy from a subsurface source into the atmosphere. While natural gas is considered a solution for a move away from higher emission coal, underreporting of these emissions would make gas look like a lower emission fossil fuel than it really is. This could affect the optimal domestic emission reductions strategies elsewhere. Thus, this thesis investigates the scientific foundation of these effects and provides a…

▼ There is growing evidence that real world, on-road emissions from mobile sources exceed emissions determined during laboratory tests and that the air quality, climate, and human health impacts from mobile sources might be substantially different than initially thought. Hence, there is an immediate need to measure and model these exceedances if we are to better understand and mitigate the environmental impacts of mobile sources. In this work, we used a portable emissions monitoring system (PEMS) and artificial neural networks (ANNs) to measure and model on-road fuel consumption and tailpipe emissions from Tier-2 light-duty gasoline and diesel vehicle. Tests were performed on at least five separate days for each vehicle and each test included a cold start and operation over a hot phase. Routes were deliberately picked to mimic certain features (e.g., distance, time duration) of driving cycles used for emissions certification (e.g., FTP-75). Data were gathered for a total of 49 miles and 145 minutes for the gasoline vehicle and 52 miles and 165 minutes for the diesel vehicle. Fuel consumption and emissions data were calculated at 1 Hz using information gathered from the vehicle using the onboard diagnostics port and the PEMS measurements. Route-integrated tailpipe emissions did not exceed the Tier-2 emissions standard for CO, NOX, and non-methane organic gases (NMOG) for either vehicle but did exceed so for PM for the diesel vehicle. We trained ANN models on part of the data to predict fuel consumption and tailpipe emissions at 1 Hz for both vehicles and evaluated these models against the rest of the data. The ANN models performed best when the training iterations (or epochs) were set to larger than 25 and the number of neurons in the hidden layer was between 7 and 9, although we did not see any specific advantage in increasing the number of hidden layers beyond 1. The trained ANN model predicted the fuel consumption over test routes within 5.5% of the measured value for both gasoline and diesel vehicles. The ANN performance varied significantly with pollutant type for the two vehicles and we were able to develop satisfactory models only for unburned hydrocarbons (HC) and NOX for diesel vehicles. Over independent test routes, the trained ANN models predicted HC within 12.5% of the measured value for the gasoline vehicle and predicted NOX emissions within 3% of the measured values for the diesel vehicle. The ANN performed better than, and hence could be used in lieu of, multivariable regression models such as those used in mobile source emissions models (e.g., EMFAC). In an 'environmental-routing' case study performed over three origin-destination pairs, the ANNs were able to successfully pick routes that minimized fuel consumption. Our work demonstrates the use of artificial neural networks to model fuel consumption and tailpipe emissions from light-duty passenger vehicles, with applications ranging from environmental routing to emissions inventory modeling.

▼ This research develops an optimization model for eco-driving at signalized intersection. In urban areas, signalized intersections are the “hot spots” of air emissions and have significant negative environmental and health impacts. Eco-driving is a strategy which aims to reduce exclusive fuel consumption and emissions by modifying or optimizing drivers’ behaviors. With the help of vehicle-to-vehicle (V2V) communication and vehicle-to-infrastructure communication (V2I), eco-driving could utilize the signal phase and the queue-discharging time information to optimize the speed trajectories for the vehicles approaching an intersection in order to reduce fuel consumption and emissions. A few research studies have been conducted on the development of algorithms that utilize traffic signal information to reduce fuel consumption and emissions. Hence, the goal of this research is to develop an optimization model to determine the optimal eco-driving trajectory (the speed profile) at a signalized intersection, which aims to achieve the minimization of a linear combination of emissions and travel time. Then enumeration method, simplex optimization and genetic algorithm are investigated to determine a practicable and efficient method to solve the proposed optimization problem. As various scenarios of distance from the vehicle to the intersection, queue discharging time and weights of emission/travel time will lead to different optimal trajectories and different emissions and travel times. A sensitivity study is conducted to analyze and compare the performance of the optimal solution in various scenarios of different such parameters. In addition, a baseline study is conducted to investigate the benefits of eco-driving when drivers only decelerate in advance but not apply the recommended speed trajectory. The results of case study show that genetic algorithm is a preferred method to solve the proposed optimization problem; Eco-driving could achieve satisfied reduction in emissions without significantly increasing travel time and emissions is more sensitive to various scenarios than travel time; Eco-driving still could achieve reduction in emissions as long as the drivers decelerate earlier even though the they would not apply the recommended speed trajectory under certain conditions.

▼ Methane (CH4) is a greenhouse gas that is emitted from natural peatland ecosystems due to their high water tables. However, large areas of natural peatlands have been drained for agricultural purposes, resulting in a reduction in overall methane emissions. However, where soil is saturated, such as within or adjacent to drainage ditches, methane emission can remain high. The aim of this research was to determine the magnitude of soil- and drainage ditch-derived methane emissions from a drained Waikato peatland under dairy grazing and where and when these emissions occur. Gamma Farm is a pastoral dairy farm located on the remnants of the Moanatuatua peatland and drained by shallow surface “spinner” drains that discharge into deeper field-border drains. The paddocks were classified into four different landforms based on the location and hydrology of the drainage features. These landforms are crown, slope, ditch edge and drainage ditch. To adequately determine the spatial and temporal variation in methane fluxes chamber measurements of methane fluxes were undertaken along a transect across the width of the study site, approximately perpendicular to the border drains. A campaign approach was used, with chamber measurements being undertaken from autumn through to winter to capture methane fluxes under different environmental conditions. To measure seasonal and annual-scale methane emissions an eddy covariance flux tower was used. Based on chamber measurements drainage ditches were shown to have average methane emissions of 0.071 ± 0.005 mg CH4 m-2 h-1 . Conversely, the soil of the crown, slope and ditch edges were shown to be a net methane sink, with average net methane oxidation of ‒0.019 ± 0.006, ‒0.01 ± 0.008 and ‒0.023 ± 0.006 mg CH4 m-2 h-1 respectively. Weighting the chamber measurements by landform area it was concluded that the study site was primarily a minor net methane sink. However, eddy covariance measurements indicated that the study site was a net source of methane with annual emissions of 44.72 kg CH4 ha-1 yr-1 . This large discrepancy between the chamber and eddy covariance measurements is likely caused by the large spatial and temporal scale differences between the two measurement techniques. In addition, it was found that there was no relationship between soil methane fluxes and the soil temperature, Olsen-P, and nitrate concentration. However, methane fluxes were shown to decrease as the ammonium concentration and depth to the water table increased. In addition, methane fluxes decreased as volumetric moisture content (VMC) decreased, but at low VMCs (<40%) methane fluxes tended towards zero. For the water-borne methane fluxes there was no relationship found between methane fluxes and any measured variable (pH, dissolved oxygen, electrical conductivity, water temperature, water depth, nitrate concentration or dissolved phosphorus). However, at longer time scales such as monthly averages of eddy covariance measurements, methane fluxes were positively correlated with soil temperature and air… Advisors/Committee Members: Campbell, David I (advisor).

This research aimed to improve the method to calculate offshoring of emissions to understand if developed countries were increasingly offshoring emissions towards developing countries. By offshoring, developed countries can achieve their climate goals without improving their carbon efficiencies. The widely-used method of the balance of emissions embodied in trade (BEET) is not a suitable method to calculate offshoring because it is influenced by differences in technologies between countries. Therefore, it may seem that countries are offshoring emission-intensive industries, while in reality, they are improving their domestic carbon efficiencies. To deal with this issue, previous work adjusted the BEET for technology differences between countries by adjusting for differences in emission intensities based on output. We proposed to use the value-added instead of output to adjust the emission intensities to deal with the issue of double-counting. We used both technology adjustments to calculate the BEET for the years from 2000 to 2014 using a multi-regional input-output analysis with data from the World Input-Output Database 2013 and 2016. Globally, offshoring was not increasing during this period and stabilized at less than 5% of global emissions for both technology adjustments. Furthermore, using linear regression analysis, we did not find a relationship between income and specialization towards emission-intensive industries. This result suggests that developed countries were not displacing emission-intensive industries towards developing countries. Finally, we found that the differences in emission intensities between countries were not only caused by differences in technologies, but also by the heterogeneity of firms aggregated within the same sector. However, with increased sector granularity, this limitation of both technology adjustments decreases. While the value-added adjustment solved the issue of double-counting, it had the limitation that firms differ in their value-capturing ability. Therefore, we concluded that the value-added adjustment was not a significant improvement of the output adjustment.

▼ This research is composed of three main topics. First, the importance of transport to ozone pollution in the U.S. Mid-Atlantic. Second, the impact of emissions and climate change on future ozone concentrations in the U.S.. Third, the effects of future emission reduction scenarios on ozone pollution in the U.S. ? Ozone is a secondary pollutant which forms in the presence of it's precursors (NOx and VOC) and solar radiation. High levels of ozone are positively associated with asthma incidence and daily non-accidental mortality rate. In 2016, 90% of non-compliance to the national ambient air quality standards (NAAQS) was due to ozone whereas only 10% was due to particulate matter and other regulated pollutants. Climate change, through creating atmospheric conditions favoring ozone formation, has been and will continue to increase ozone concentrations in many parts of world including the U.S. ? First study focuses on ozone transport in the U.S. Mid-Atlantic region where high levels of ozone are due to high emissions and transport of ozone precursors from upwind states. Therefore, local emission reductions are not the most effective way to reach attainment in these areas. In this study we used two air quality models with source apportionment methods to study the extent of ozone precursor transport in the Mid-Atlantic and the efficacy of emission-reduction strategies, with a focus on Delaware. We found that in Delaware reducing local emissions of NOx and VOC by 20% is minimally effective, and the same emission reduction in each of five upwind states individually lowers ozone but not sufficiently to reach attainment. Only a consorted effort by the five upwind states together can lower Delaware ozone significantly. The emission reduction needed by the five states together is approximately 10%, half that of each individual state. This suggests that coordinated efforts and long-term, multi-state strategies are necessary to protect air quality in the Mid-Atlantic. ? In the second study, the non-linear response of future ozone levels to both meteorological conditions and emissions are studied by linking global climate models to regional meteorological and air quality models. The regional climate in 2016 and in 2050 under the Representative Concentration Pathway 8.5 (RCP 8.5) is simulated using the Weather Research and Forecasting (WRF) model to downscale 3-year summer time slices from the Community Earth System Model (CESM). The downscaled meteorology is then used with the Comprehensive Air Quality Model with Extensions (CAMx) to simulate air quality during each of these 3-year summer periods over the nine climate regions of the continental U.S.. We considered three cases for this study. The control case with 2016 meteorology and 2016 emissions is compared against two future scenarios. The first future scenario includes only the meteorological effects of climate change, without any additional emission reductions, thus with the same emissions as today. The second future scenario includes the effects of both climate change and… Advisors/Committee Members: Archer, Cristina L..

▼ Unlike other transportation sectors where pollutant emissions usually occur only near the Earth’s surface, aviation emissions happen primarily at altitudes of 8-12 km above the surface, impacting the upper troposphere and the lower stratosphere (UTLS). At these altitudes, the pollutants can contribute significantly to greenhouse gas (GHGs) concentration and to the formation of secondary aerosol, which can have an impact on climate change. This thesis has two parts: the first part examines the capabilities of a simplified model that is used by the U.S. Federal Aviation Administration (FAA) for considering the impacts of aviation emissions in policy-related studies; the second part examines the regional effects on climate forcing resulting from aviation emissions. Most previous studies have focused on aviation effects on climate using globally-averaged metric values, which do not give information about the spatial variability of the effects. While aviation emissions have significant spatial variability in the sign and magnitude of response, the strength of regional effects is hidden due to the global averaging of climate change effects. In this study, the chemistry-climate Community Atmosphere Model (CAM-chem5) is used in analyses to examine the regional climate effects based on 4 different latitude bands (90oS- 28oS, 28oS-28oN, 28oN-60oN, 60oN-90oN) and 3 regions (contiguous United States, Europe and East Asia). The most regionally important aviation emissions are short-lived species, such as black carbon and sulfates, emitted from aircraft directly, and O3-short induced by NOx emission indirectly. The regionality of these short-lived impacts are explored and compared to the globally-averaged effects. Studying aviation emission on climate usually relies on computationally expensive chemistry-climate models. However, for aviation policy analyses, a wide range of different scenarios need to be evaluated, making the development of simple models like the Aviation environmental Portfolio Management Tool (APMT), developed for the FAA by MIT, very useful. We evaluate how well the model determines climate effects from aviation based on the Aviation Climate Change Research Initiative (ACCRI) findings and more recent analyses. We test the Carbon Cycle and Energy Balance model of APMT, and explore the non-linearity effects in using such a simplified model. Advisors/Committee Members: Wuebbles, Donald James (advisor).
